Visits to this blog over the past month were Internet Explorer 44%; Firefox 29%; Chrome 12% and Safari 10%.
A Google search for most popular browser shows Internet Explorer generally reported as number one, but losing market share. Chrome, the browser I use, is gaining.
I switched from Internet Explorer to Firefox several years ago when they had security problems, then switched to Chrome which works better with the suite of other Google products I rely on, including for this blog. However, if having the Genealogy in Time toolbar is important to you then you're out of luck with Chrome.
